DEVICE To FAGILITATE [DYING- OF SPINDLE-BANDS.

Specification of Letters Patent.

Patented May 2, 1916.

Application filed January 15, 1916*. Serial No. 72,294.

I To all whom it may concern V I is a specification.

lhis invention is a simple and easily manipulated device by the use of which the operator may apply the driving band or belt to the whorl of a spindle with any deslred degree of tension.

At the present time, so far as we are aware, it is the practice to oin the ends of the driving band or belt at a point below the whorl of a spindle which point is at a less distance from the driving pulley or cylinder than the surface of the whorl around which the belt passes in the operation of the spinnlng machine. As a result of this practlce, when the belt is slipped over and onto the whorl the tension of the belt is increased so that an unnecessary strain is placed on the belt and on'the splndle causmg excessive wear upon the belt and other parts of the spinning ma-. chine and also causing great loss of power in driving the spinning machine.

This invention provides an apparatus which may be readily applied to and removed from the spindle of any spinning machine and by the use of whichthe belt may be tied with any desired tension and easily fitted to the spindle whorl. When the belt so tied is fitted to the spindle whorl, it will drive the same withjustthe proper tension needed for the particular construction of the machine and the work to be done and will not pull'the spindle out of its perpendicular position so that the product of the machine will be uniform in quality and wear upon the spindle and its parts will be reduced with a corresponding increase in the durability of the spindle.

The invention is illustrated in the accompanying drawings and will be hereinafter fully described, the novel features being sub sequently particularly pointed out. in the claims following the description.

In the drawings: Figure 1 is a plan view of a spindle and its mounting showing our improved device fitted thereto; Fig. 2 is a similar view, the latch being omitted and a portion of the oil cup being broken away;

Fig. 3 is a perspective view of our improved device; Fig. 4 is an end view of the device showlng so much of the spindle and its mounting as will aid in an understanding of the operation of the invention.

The spindle 1 may be of any preferred construction and is equipped with the usual whorl 2 and mounted in the ordinary manner.

In carrying out our invention, we employ a substantially U-shaped frame comprising an upper plate 4, a lower plate or arm 5 and a standard or connecting plate 6 which spans the space between the upper and lower plates and joins the same as clearly shown in the drawings. The upper plate or arm 4: is provided with a notch 7 in its free end or edge which is adapted to fit around the upper end of the bracket or bearing 8 in rail 3 in the which the spindle is mounted while the lower arm or plate 5 is provided with a longitudinal slot 9 adapted to fit over the lower end of said bracket or bearing. Upon the outer side of the bridge or connecting plate 6 we pivot the latch or-locking arm 10 which. depends from its pivot 11 and is then turned inwardly at an angle corresponding to the angle between the members 5 and 6 thereby providing a bearing arm 12 having its free end arranged to bear against the lower end of the bearing or bracket in which the spindle is mounted, as shown most clearly at 13 in Fig. 2. Upon the upper side of the top plate 4 is slidably mounted a yoke 14, the arms of which are disposed at opposite sides of the spindle and the whorl upon the same. These arms 15 are tapered at their extremities, as shown at 16, whereby they will offer no obstruction to the movement of the belt or band in placing the same in position. The head or transverse memberl'? of this yoke is extended vertically and at one side is constructed with an overhanging finger 18 which is adapted to engage over the belt while the same is being tied. Upon the side of this expanded head of the yoke is fulcrumed the releasing lever or cam 19 which has one face grooved, as indicated at 20,; or otherwise constructed to engage the belt and retain the same in position while the ends are being united. This cam or releasing lever normally occupies the position shown in Figs. 1, 2 and 3, and in dotted lines in Fig. 4, so that the branches or members of the belt will be retained in such position that the ends may be easily united. After the ends of the belt have been joined, the outstanding arm or handle member 21 of the lever is swung up to the position shown in fulllines in Fig. 4, thereby turning the groove into a substantially vertical position and lifting one side or run of the belt over the yoke, whereupon the tension or strain to which the belt has been subjected during the tying operation will pull-the belt over and into the groove of the whorl 2, as will be readily understood. I A lug 22 depends from thehead 17 of the yoke through a slot 23 in the plate 4 and the lower end of this lug is secured to one end of a bolt 24 which is slidably mounted ina housing or bracket 25 secured to the underside of said plate. The bolt is guided in its movement by the standard 6 and a guide 26 provided on the under side of the plate 4, and a spring 27 disposed within thehousing, bears upon the bolt so as to hold the same normally in its outermost position. It will be readily understood that, when the ends of the belt are brought around the yoke 14 and are tied together,

the belt will exert a pull upon the yoke in opposition to the tension of the spring 27 and'the operator can readily adjust the tension of the belt by pulling upon the same so that it will overcome the tension of the said spring to a greater or less degree. The belt can thus be set so as to exert any desired tension upon the whorl and, consequently, will be adapted to light or heavy work as circumstances may demand. In order that the operator may have a definite knowledge of the tension to which the belt has been set, we provide an indicator or pointer 28 which is secured upon the outer end of the bolt 24 and projects therefrom over the upper plate 4 as clearly shown in the drawings, a series of graduations 29 being marked in any convenient manner upon the upper surface of the plate 4' according to predetermined calculations so that the end of the indicator or pointer will show by its position the degree of tension to which the belt has been set.

It is thoughtthe use and advantages of our improvedrdevice will be readily understood from the foregoing description taken in connection with the accompanying draw- The spindle is mounted in the usual or any preferred manner and the belt, indicated by'dotted lines at 30 in Fig. 1, is passed around the driving pulley or cylinder and its ends brought around the yoke 14, with the side members or runs of the belt engaging the grooves 20 in the cam or lever 19, and passes through the space between the overhanging finger 18 and the adjacent sidemember of the yoke, the base or inner wall of said space being beveled, as indicated most clearly at 31 in Fig. 4, so as to prevent cutting or unnecessary wear upon the belt. In fitting our improved device to the spindle, the locking member 10 is swung to the position shown in Fig. 3 thereby pulling the arm 12 out of the plane of the spindle and its bearings so that the device may be tilted sufficiently to permit the longitudinal slot 9 to be engaged over the lower end of the spindle bracket or bearing. The device is then swung upwardly so that the notch 7 will pass around the upper end of the bracket just below the whorl, as is shown in Fig. 2. When the belt, therefore, is drawn around the outer side of the yoke 14 it will be substantially in the horizontal plane of the groove of the whorl so that, when the belt is released from the yoke, it will pass directly into its operative engagement with the whorl. After the device has been fitted in position, as just described, the locking arm 12 is swung into the vertical plane of the U-shaped frame consisting of the members 4, 5 and 6, and will lie directly under the lower plate 5, as shown in Figs. 2 and 4, so as to bear against the lower end of the spindle mounting and thereby prevent tilting of the device. After the belt has been fitted and released by manipulation of the lever 21 and cam 19, as heretofore stated, the arm 12 is again swung to the position shown in Fig. 4 whereupon the device will readily tilt downward and outward so as to be released from the spindle mounting. The spinning machine may then be operated in the usual manner.

It will be readily noted that we have provided an exceedingly simple device which may be easily applied to or removed from any spindle and by the use of which the belt may be easily and quickly tied and engaged around the whorl.
